Description

2-(2-Hydroxyethoxy)Benzaldehyde is a versatile aromatic aldehyde derivative featuring a hydrophilic ethoxyethanol side chain. This unique bifunctional structure makes it a valuable intermediate for synthesizing more complex molecules in advanced chemical manufacturing. It is particularly sought after by R&D chemists and production specialists in the pharmaceutical, agrochemical, and specialty polymer industries for creating novel compounds with tailored properties.

Application

• Pharmaceutical Intermediate: A key building block in the synthesis of active pharmaceutical ingredients (APIs), particularly for compounds requiring ether-linked aromatic systems.
• Agrochemical Synthesis: Used in the production of herbicides, fungicides, and plant growth regulators where its aldehyde group facilitates the formation of various heterocycles.
• Polymer & Resin Modifier: Serves as a monomer or cross-linking agent in the production of specialty polymers, epoxy resins, and coatings to introduce aldehyde functionality and improve solubility.
• Ligand & Chelating Agent Precursor: The aldehyde and ether oxygen atoms make it a useful starting material for synthesizing Schiff base ligands used in catalysis and metal complexation.
• Fine Chemical & Flavor/Fragrance Intermediate: Employed in the multi-step synthesis of complex aromatic compounds for flavors, fragrances, and dyes.
• UV Absorber & Stabilizer Synthesis: Acts as a precursor in the manufacture of benzophenone and benzotriazole derivatives used as light stabilizers in plastics and coatings.

Quality Control

Every batch of 2-(2-Hydroxyethoxy)Benzaldehyde is produced and tested under a strict quality management system. We provide comprehensive analytical documentation to ensure traceability and consistency for your critical processes. A detailed Certificate of Analysis (COA) is supplied with each shipment, confirming identity, purity, and conformance to agreed specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C). Due to its sensitivity to light and potential for oxidation, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation. Keep away from strong oxidizing agents and heat sources.
